Joe Monk's and Radoslaw's comments appear well-informed. And with 9-track I believe there's no need to deal with the abomination of even parity. ( knew an old CDC OS that relied on the difference to discern filetypes, even replicating the behavior in DASD files.)
It's a pity there's no facility to process AWSTAPE directly with no need for a step to convert to virtual or real 3480. Subsystem? ISV? Or to generate AWSTAPE on Linux, MacOS, or Windows. Does a dump of the first block say "VOL1"? If the OP believes the tapes contain useful data he probably knows which utility can process the restored images. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
